1.So how do you find an engram?

那怎么找到记印迹？

2.Now the next question was whether altering the neurons in the engram would mess with the memory.

下一个问题变记印迹中的神经元，扰乱记。

3.But, if manipulating engram cells can add, delete, and modify memories in predictable ways, that does mean engrams are a useful model for studying memory.

但，如果操纵记印迹细胞能以可预测的方式增加、删除记，那就意味着记印迹研究记的有用模型。

4.The word scientists use to talk about this physical trace of a memory in a brain, the pattern of cells that activate to recall a memory, is an engram.

科学家用来谈论大脑中记的物理痕迹，即激活回记的细胞模式，一个记印迹。

5.The researchers taught a mouse to associate a sound with a shock and then pumped the engram cells, where they knew that memory lived, full of this light-sensitive protein.

研究人员教一只老鼠把声音电击联系起来，然后给他们所知道的记存在的部位注入记印迹细胞，细胞中充满这种感光蛋白。
